Êtes-vous américain, monsieur?

[pne]

I just saw a guy and a girl talking in what sounded like Croatian... and the guy sounded so American to me!

It sounded so weird to me to hear someone speaking fluent Foreign... with an American accent.

I guess it just sounds a little incongruous to me. But more power to him if that was indeed the case! Learning another language is always cool, especially if you can carry on a fluent conversation and be understood, never mind having an accent.
